I think of these sorts of things as sort of the networking equipment of drug side effects--an undesirable side effect of things that are otherwise desirable. Now, reasonable people can disagree as to the relative importance of the good and bad effects, but absent evidence to the contrary, I generally assume that people are able to make those choices for themselves. I'm not sure what you mean by routing above. Are you suggesting there's some negative externality in that NAT makes the routing infrastructure more complicated? If so, what is it? -Ekr -- [Eric Rescorla ekr@rtfm.com] http://www.rtfm.com/
